You are meddling with powers you cannot possibly comprehend !

Deep ! This is getting into the boost bottle / mojo territory !

Get a folding tip leavers, set at about 30 degrees. Any higher makes it a pain to change gear, and virtually impossible in a section.

WD now make a chain lube ? https://wd40.co.uk/specialist-motorbike/chain-lube/

1 tooth may be enough.

Split link as usual. Only mentioned the rivet option if your trying various sprocket combos.

Regina chain has proper rivets, so you can add bits in without using multiple split links. In motion sell suitable 1/2 links.

Regina are pretty good, I wash with petrol, blow off / dry. Use putoline dx 11. Chains last well in local conditions. I've been buying regina chains for £20.

If your problem started after a fall, chances are you damaged something to cause the problem. Check all connections, look for damaged/crushed wiring. Re-seal the exhaust to eliminate that, same with throttle body, reduce tickover till it sounds correct.

Zundapp's, Cz's and mz's are still in use in Germany, very successfully. @pschrauber any pictures you can post easily ?

Or you could try one of these to remove seals https://www.ebay.co.uk/p/Lisle-58430-Shaft-Type-Seal-Puller/6022165661?iid=400337849154

What he said.

Unplug the kill switch from the circuit, ride home ......

David 14 : 2 In my fathers house there are many Rotax parts. If it were not so I would have told you .....

@tshock250 Your father will probably have some " under the bench " that he could compare ?

Is the jumbo shaft the same as earlier 240 / 280's ? Never tried it myself, but the person who mentioned it works extensively on tl's and tx300's.

This is on a sharan, one of the springs in the dual mass FW made a bid for freedom through the circumference of the FW. Caught it just in time. Just the housing thats slightly scored. Flywheel / clutch had 122k miles which is pretty good value.

Think the o/p is still trying to work out what "wrong " means ......

I hope not, mine just tried to eat its way through the gear box !

My B40 has the frame no on the left (as your sitting on it) front engine mount.

Think Fantics had marzzochi's ? If so use 2 IMO.

If it was mine I'd put the seal in the "wrong" way round. Got to be worth a try ?
